HARROW-FRAME.

SPECIFICATION forming part of Letters Patent No. 269,494, dated December 19, 1882. Application filed August 9. 1882 (No model.)

To all whom it may concern Be it known that I. JAMES H. WINN, of Benicia, in the county of Solace and State of California, have invented a new and useful Improvement in Harrow-Frames; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to an improvement in making barrows; and it consists principally in the improved construction of the harrowframe and in the manner of fastening the teeth therein, as shown and hereinafter explained.

In the drawings, Figure l is a side view of the section of the frame, showing two teeth in position. Fig. 2 is a cross-section on the line a: w.

I construct my barrow-frame of bars A A, of angle-iron, of any desired length or thickness, and adapted to be formed into a frame of any suitable shape and to hold any required number of teeth. These bars A Aare reversed, and in that position are clamped together by bolts 1) b, so that they form practically a hollow rectangular box or tube. The upper and lower plates of these angle-irons are perforated at points opposite, and through these perforations pass the barrow-teeth G, as shown in Fig. 2.

It will be evident that my barrow-frame, be sides being exceedingly light, since it is practically a tube. possesses great strength, and

that it is exceedingly simple in construction.

'in the frame of a. barrow, as I am aware that single rails constructed or iron of that shape have been used before.

What I claim is 1. A harrow-tranie constructed of bars A A. of an gle-iron, clamped together so as to form a rectangular tube, substantially as described.

2. The barrow-frame consisting of the reversed right-angle bars A A, in combination with the teeth, and with the clamping-bolts b I), placed on each side of said teeth, all substantially-as described.

In testimony whereot'l have signed myname tothis specification in the presence of two subscribing witnesses.

JAMES H. WlNN.
